![]() In this compatible format, two commas are If the list argument is omitted, the command output is compatible with earlier versions of lscpu. p, -parse Optimize the command output for easy parsing. h, -help Display help information and exit. When specifying the list argument, the string of option, equal sign (=), and list must not contain any blanks or other white space. If the list argument is omitted, all columns for which data is available are included in the command output. e, -extended Display the CPU information in human readable format. This option may only be specified together with option -e or -p. c, -offline Limit the output to offline CPUs. b, -online Limit the output to online CPUs (default for -p). This option may only specified together with option -e or -p. Options -a, -all Include lines for online and offline CPUs in the output (default for -e). This column contains data only if your hardware system Vertical The workload is concentrated on few CPUs.įor vertical polarization, the column also shows the degree of concentration, high, medium, or low. Horizontal The workload is spread across all available CPUs. POLARIZATION This column contains data for Linux instances that run on virtual hardware with a hypervisor that can switch the CPU dispatching mode (polarization). This column contains data only if your hardware system and hypervisor support dynamic CPU resource allocation. ONLINE Indicator that shows whether the Linux instance currently makes use of the CPU.ĬONFIGURED Indicator that shows if the hypervisor has allocated the CPU to the virtual hardware on which the Linux instance runs. A node may contain several books.ĬACHE Information about how caches are shared between CPUs. A socket can contain several cores.īOOK The logical book number. If an unsupported column is specified, lscpu prints the column but does not provide any data forĬolumns CPU The logical CPU number of a CPU as used by the Linux kernel.ĬORE The logical core number. Not all columns are supported on all architectures. The column labels are not case sensitive. See COLUMNS for a list of valid column labels. Specify a comma-separated list ofĬolumn labels to limit the output table to only the specified columns, arranged in the specified order. Use this argument to customize the command output. ![]() ![]() Options that result in an output table have a list argument. The CPU caches and cache sharing, family, model, bogoMIPS, byte order, and stepping. The information includes, for example, the number of CPUs, threads, cores, sockets, and Non-Uniform Memory Access (NUMA) nodes. Output can be optimized for parsing or for easy readability by humans.
